The Frenchman, 33, scored his fifth goal since the restart in Sunday's 3-1 win over Manchester United in the FA Cup semi-final.
And Lampard was full of praise for the World Cup winner when speaking after the match.
He said: “He sets an amazing example. He kept training well, had the most positive attitude possible and he just exudes professionalism.
“I know what he can do, the presence and quality he has. We have to make sure we work off and around him but he's been great and the young players should see in him everything it takes to be a professional."
